BACKGROUND AND PURPOSE Candida species constitute an important group of opportunistic fungi, which cause various clinical diseases. Considering the resistance of some Candida species to conventional antifungal agents, treatment of such cases may be challenging and complicated. The purpose of this study was to evaluate and compare the antifungal activities of Euphorbia macroclada latex and fluco...

Overexpression of the multidrug efflux pump MDR1 is one mechanism by which the pathogenic yeast Candida albicans develops resistance to the antifungal drug fluconazole. The constitutive upregulation of MDR1 in fluconazole-resistant, clinical C. albicans isolates is caused by gain-of-function mutations in the zinc cluster transcription factor Mrr1. It has been suggested that Mrr1 activates MDR1 ...

The aim of the present study was to investigate the antifungal activity of Zatariamultiflora essential oil, fluconazole and ciclopirox olamine against 44 non-albicansCandida isolates from patients with recurrent vulvovaginal candidiasis. A set of C.glabrata (29 strains), C. krusei (3 stains) and C. patapsilosis (2 strains) were studiedusing Clinical and Laboratory Standards Institute (CLSI) bro...

OBJECTIVE To determine the proportion of albicans and non-albicans candiduria in a hospital setting and to ascertain if fluconazole is still suitable as empirical antifungal therapy based on antifungal susceptibility patterns of Candida species. METHODS The cross-sectional study was conducted between December 2010 and December 2011 at UKM Medical Centre, Kuala Lumpur, Malaysia and comprised 6...

The present study demonstrates the efficacy of anidulafungin on mature Candida albicans biofilms in vivo. One hundred fifty-seven catheter fragments challenged with C. albicans were implanted subcutaneously in rats. After formation of biofilms, rats were treated with daily intraperitoneal injections of anidulafungin for 7 days. Catheters retrieved from treated animals showed reduced cell number...

conclusions these findings highlight the importance of precise and correct species identification of clinical yeast isolates via molecular approaches, and of monitoring the antifungal susceptibility of candida species recovered from clinical sources. laboratories should consider routine mic testing of c. glabrata isolates collected from sterile sites. surveillance studies of candida species and...

We studied six clinical isolates of Candida albicans. All six isolates showed high level resistance to fluconazole (minimum inhibitory concentrations 64 microg/ml) with varying degrees of cross-resistance to other azoles but not to amphotericin B. Neither higher dosage nor upregulation of the gene encoding the cytochrome P- 450 lanosterol 14 alpha-demethylase (CYP51A1 or P-450LDM) was responsib...

OBJECTIVES To investigate the in vitro antifungal susceptibility pattern of 375 Candida albicans bloodstream isolates recovered during the European Confederation of Medical Mycology survey of candidaemia performed in Lombardia, Italy and to test the ability to form biofilm. METHODS In vitro susceptibility to flucytosine, fluconazole, itraconazole, posaconazole, voriconazole and caspofungin wa...

Candida albicans is the most frequent opportunistic fungal agent in human being. One of its virulence factors is phenotypic switching. In this study, we investigated the susceptibility of different phenotypes of C. albicans, obtained from clinical specimens, to fluconazole (FLZ) and voriconazole (VRZ) with microdilution reference method. In this study, 281 C. albicans of six different phenotype...

The dimorphic fungus Candida albicans excretes farnesol, which is produced enzymatically from the sterol biosynthetic intermediate farnesyl pyrophosphate. Inhibition of C. albicans by four azole antifungals, fluconazole, ketoconazole, miconazole, and clotrimazole, caused elevated farnesol production (10- to 45-fold). Furthermore, farnesol production occurs in both laboratory strains and clinica...
